  set_node_attrs("shape", "circle")

# Get the graph's internal ndf to show which
# node attributes are available
get_node_df(graph)
#>   id type label value  shape
#> 1  1 <NA>     1   2.0 circle
#> 2  2 <NA>     2   8.5 circle

# Rename the `value` node attribute as `weight`
graph <-
  graph %>%
  rename_node_attrs("value", "weight")

# Get the graph's internal ndf to show that the
# node attribute had been renamed
get_node_df(graph)
#>   id type label weight  shape
#> 1  1 <NA>     1    2.0 circle
